Legion, we got another newbie.

Listen rookie, not to be rude, but novels based off videos games are normally non-canon to the game since they take certain liberties with the source material, such as saying all of Nero's weapons besides Yamato melted when he was in the Savior. That's all I can think off the top of my head but really you should take what's stated in the novel with a grain of salt and I'd ask Legion for more info.

The only reason people even consider Nero to possibly be the son of Vergil is 1.)They're theorists who want Vergil to be the main star of the series for some reason and what him hammered into as much as possible. 2.)It's a fan rumor that got way too big way too fast. 3.)New fans(like you, no offense meant) think everything DMC related is canon to the series. and 4.)People cannot comprehend the meaning of developers wanting to keep things mysterious, they want to keep people guessing. It's never been offically stated Nero is Vergil's kid. The novel hints at it(even though it's non-canon). Just because a novel HINTS at it does not mean that's true. Hell for all we know Nero could be the son of Sparta's cousin for all we know. But we will never find out because Capcom will never go back to the true Devil May Cry series.
